Strange Connection issues - Raspberry Pi and Respeaker 4 Speaker Array

Okay I got it going. Turns out I only need to try and push SSL and SST through TCP, so I kept the IP address there and used the defaults under the SSS configurations. For example:

type = "file" path = "postfiltered.raw"

Now it's working, but I hit errors after running it for a few minutes. The error is reading
Segmentation Fault

Will keep working on it.

Hi, what you experience is ODAS not able to sink the audio streams to ODAS Studio (odas_web).

With the correct IP, ODAS immediately connects to the Studio and raise the "cannot sink hops" error. With the incorrect IP, the timeout while the audio sockets attempt to connect allow the data sockets to stream for a few seconds before the error occurs. That's why using the wrong address seems to "fix" the problem.

Looking at your configuration file I would first make sure you configure ODAS Studio to use de 44100 Hz you set as an audio sink frequency as ODAS Studio is configured for 16000 Hz by default. You could also change your sink frequency to 16000 Hz.

The default file interface saves the audio as files on the machine running ODAS, in this case, the Pi. If you are ok with no audio stream, you can set the interface to blackhole and the type to undefined, like the classify output. This will suppress the audio streams.

For the segmentation fault error, it's pretty hard to investigate, more so if it occurs after a few minutes. The ODAS repository will be more helpful for that one.
